SN74ALS323DWE4

Logic - Shift Registers are a type of digital logic circuits used to move data within, or between, digital circuits. The SN74ALS323DWE4 is an 8-bit, low-voltage, low-power, bi-directional shift register suitable for use in a variety of applications. It is an integrated device, combining three functions and allowing data to be transferred or shifted horizontally, or sequentially, while also providing logic functions.

Description

The SN74ALS323DWE4 is based on the ALARM chip, which contains eight flip-flops and a logic gate, making it ideal for data transfer, modulation and registration. Each flip-flop has its own data, clock and set/reset inputs, and its own output, making them more efficient when compared to other shift registers. The logic gate within the ALARM chip is used to determine whether data is to be shifted within the register or into the register from an external source. The SN74ALS323DWE4 has a built-in priority encoder input, which can determine the priority of the data within the register.

Features

• 8-bit, low-voltage, low-power, bi-directional shift register
• Each flip-flop has its own data, clock and set/reset inputs and its own output
• Built-in logic gate
• Priority encoder input
• Power supply of ±5V DC
• Packaged in a standard 20-pin Dual Inline Package

Application Fields

The SN74ALS323DWE4 is used in logic-level applications, such as logic registers, serial analog-to-digital/digital-to-analog conversion as well as data transmission and input/output. It is frequently used for data manipulation and analysis, such as broadcast television applications, clock conversion, frequency analysis and pulse-width modulation.

Working Principle

The SN74ALS323DWE4 is designed to transfer data between two or more digital logic gates. A logic gate is an exclusive or (XOR) gate, which requires two inputs and provides two outputs. The operation of XOR is that when both inputs are 1 or both are 0, the output is 0; when one input is 1 and the other is 0, the output is 1. XOR gates are used to shift the data within the register, or to shift data into the register from the external sources.

The logic gate within the ALARM chip is used to determine which input data is to be shifted. This is done by the priority encoder which is connected to the ALARM chip\'s logic gate. The priority encoder also has the ability to determine the priority of the data within the register. The clock input determines when the data is to be shifted. When the clock is a 0, data is loaded into the register; when the clock is 1, data is shifted and the next value is loaded into the register.

Conclusion

The SN74ALS323DWE4 is an 8-bit, low-voltage, low-power, bi-directional shift register suitable for use in a variety of applications, from logic-level to data manipulation. Its features, such as the priority-encoder input, and its logic gate, make it an ideal device for data transfer and modulation. Its working principle is based on the XOR gates within the ALARM chip, making it an efficient device for data transfer, as well as for data both into and out of the register.
